What Spermidine is
A natural polyamine that induces autophagy, linked in population studies to lower mortality and studied for cardiovascular and cognitive aging.
Spermidine is a naturally occurring polyamine found in foods such as wheat germ and aged cheese that promotes autophagy, the cell's self-cleaning process. Observational studies link higher dietary spermidine to lower cardiovascular and overall mortality, and small human trials have examined memory and heart health.
Mechanism: Induces autophagy by inhibiting acetyltransferase activity, helping cells clear damaged components associated with aging.
Regulatory history: Sold as a supplement / food component; not an approved drug
How Health Canada treats this kind of product
Authorises drugs for sale through a Notice of Compliance and Drug Identification Number. A compound that is not authorised for sale cannot lawfully be sold for human use, and personal importation of prescription drugs is limited.
The classification above is the The Longevity Archive reading of Health Canada, Health Products and Food Branch listings for Spermidine at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
